Systemic Dysregulation of Angiopoietin-1 and -2 in Streptococcal Toxic Shock Syndrome
Bibliographic record
Abstract
Streptococcal toxic shock syndrome (STSS) is characterized by diffuse vascular leak resulting from widespread endothelial activation. Angiopoietin-1 and -2 (Ang-1 and Ang-2), which are important regulators of endothelial quiescence and activation, respectively, are dysregulated in certain diseases that are associated with endothelial dysfunction, but they have not been previously investigated in STSS. Plasma Ang-1 and Ang-2 concentrations were measured in 37 patients with invasive streptococcal infection with and without concurrent STSS. Greater angiopoietin dysregulation (decreased Ang-1 and increased Ang-2) occurred in STSS than in invasive infection without shock; dysregulation decreased with convalescence. These results suggest that systemic Ang-1 and Ang-2 dysregulation is associated with disease severity in invasive streptococcal infection and that plasma levels of Ang-1 and Ang-2 may serve as clinically informative biomarkers in STSS.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
